Numerical analysis for rotating electro-osmotic flow of fractional Maxwell fluids

In this paper, a rotating electro-osmotic flow of a fractional Maxwell fluid in a parallel plate microchannel with high zeta potentials is examined. The Navier's slip law at walls is considered. The electric double layer potential distribution is derived by using the nonlinear Poisson–Boltzmann equation. Based on the L1 approximation of the Caputo derivative, a Crank–Nicolson numerical scheme is developed for obtaining the numerical solutions of the rotating electro-osmotic flow velocity profiles. With a purpose to verify the correctness of our numerical results, a comparison has been made with the analytical solutions of the Newtonian fluid given by the previous work and the excellent agreement between the solutions is clear. Finally, the influences of the fractional parameters of α and β, the slip length d and the wall zeta potential ζ on the velocity distribution are also discussed in detail.
